Patent CA-2193144-A1 (CA)
Inventor: TRAVAGLINI NICK
IPC: F16H25/12
Filed: 1996-12-17
Abstract: A motion transfer mechanism has an elongated track upon which ride transfer mechanisms, to translate relative movements of the track into precise actuation of one or a plurality of transfer mechanisms. The track is of substantially unlimited length, in relation to the machine with which it is used, such as the press of a stacked injection mold, so as not to limit access to, or the range of motion of the press or other machine. The transfer mechanisms each rides upon the track, such that they can freely traverse its full length. The track has one or more spiral portions in its length, to translate relative longitudinal displacement into rotational movement. The angle of spiral can be varied, with local changes in angle, on order to achieve desired rates of acceleration, deceleration and periods of dwell in the operation of the output mechanism. The transfer mechanisms and the track mounting each have a simple enabling and disabling mechanism, which may be interconnected by a simple, manually operable, bang-bang hydraulic control, to enable an operator to effect operationor disablement of the system with a single hand motion. The system may be used with high cycle processes such as an injection mold, the track and motion transfer portions of the system being comprised exclusively of simple, robust, low stressmechanical components of extreme reliability, without power cylinders or other prime movers or limit switches, relays or other electronic components that collectively diminish system reliability. In the case of use of the system to introduce product take-off devices, such as suction cups between the open platenfaces of a mold, the system may be secured in "strap-on" relation to the sides of the respective components of the mold, to generate precise in-and-out actuation of the product handling devices between the mold interfaces during the ejection portion of the molding cycle in response to the normal cyclic movements of the mold.

Title: Apparatus and method for calibrating a storage tank
Inventor: HART ROBERT P
IPC: B65D90/48
Filed: 1997-01-09
Abstract: An apparatus and method are provided for calibrating a liquor storage tank. The apparatus includes a sensor disposed within the tank for sensing the liquid levels in the tank and one or more metering devices for measuring the amount of liquid dispensed into or out of the tank. A processor is also provided which is capable of determining the volume in the tank as well as the amount of liquid dispensed into or out of the tank based on liquid level measurements obtained during idle periods following dispensing periods. The processor is programmed with an algorithm which employs a mathematical function which relates either the volume of the liquid or the change in volume of the liquid per unit of associated height change of the liquid in the tank as a function of the height of the liquid in the tank and a number of calibration parameters which include the length, diameter, end shape, and tilt of the tank as well as the offset of the sensor from the bottom of the tank. The calibration routine involves searching for the calibration parameters which minimize the sum of the square of the residuals between a first set of refined data values which are derived using the measured volumes (or volumes per unit of height change) dispensed by the meter devices and a second set of estimated volumes (or volumes per unit of height change) which are derived using the mathematical expression.

Title: Bidirectional optical modulator having lightwave signal conservation
Inventor: SULLIVAN CHARLES T
IPC: G02F1/035
Filed: 1995-09-12
Abstract: A modulating optical element (10) having ports (1, 2) wherein either port can output or receive light signals. An electrooptic effect is applied to the optical element to allow the light signals to pass or not pass through the optical element. Due to the electrooptic effect in preventing signals from passing through the optic element ("off" state), light signals radiate out (50) of the optical element and are absorbed by the substrate (6) of the optical element assembly. Rather than being lost, the energy from the light signal is converted, via photodetector electrodes (7, 17), to current which may be used for other purposes in the modulator system, such as bias stabilization.
